I,ve tried to install truecrypt in grafpup with the the pets devicemapper and truecrypt and I found problems because it is said not found the truecrypt module. any idea for make it works? thanks koker

Ya sure its a command line program no gui for linux. I went to the website and made a package of the latest version. Just install it the go to you desktop and click Console and in the console type truecrypt
and it should run:)
